private void updateCustomBackgroundSummary() {
        int resId;
        String value = Settings.System.getString(getContentResolver(),
                Settings.System.LOCKSCREEN_BACKGROUND);
        if (value == null) {
            resId = R.string.lockscreen_background_default_wallpaper;
            mCustomBackground.setValueIndex(LOCKSCREEN_BACKGROUND_DEFAULT_WALLPAPER);
        } else if (value.isEmpty()) {
            resId = R.string.lockscreen_background_custom_image;
            mCustomBackground.setValueIndex(LOCKSCREEN_BACKGROUND_CUSTOM_IMAGE);
        }
        mCustomBackground.setSummary(getResources().getString(resId));
    }

이런 부분에서....

packages/apps/Settings/src/com/android/settings/cyanogenmod/LockscreenInterface.java:92: variable resId might not have been initialized
        mCustomBackground.setSummary(getResources().getString(resId));
